LIQUID RHEOS'IAT.

Application filed April 26, 1926. Serial No. 104,802.

My present invention has reference to a lighting device for gas ranges or the like, and my object is the provision of an electric lighter for this purpose in which an electrolytic cell or transformer is employed having one of its electrodes Wired to the house supply, the second electrode being wired to a fuse and from thence to a lighting electrode, the latter when brought into contact with the burner will create a spark to light the gas when the gas cock is turned on.

To the a tainment of the above broadly stated objects and others which will appear as the nature of the invention is better un derstood, the improvement resides in certain features of construction, combination and operative association of parts, a satisfactory embodiment of which is illustrated by the accompanying drawings.

In the drawings:

Figure 1 is an elevation illustrating the application of my improvement.

Figure 2 is a longitudinal sectional view through the box containing the electrolytic rectifier.

Figure 8 is an elevation of the lighting electrode, the handle portion thereof being in section.

Figure 4 is a sectional view through the electrolytic or rectifier.

Figure 5 is a View to illustrate the circuit.

Referring now to the drawings in detail, the numeral 1 designates the upper portion of an ordinary gas range and 2 one of the burners therefor. Before proceeding with the description of my improvement it may be well to state that I do not desire my invention restricted as a lighting means for gas ranges, as the same may be employed with equal eiliciency for lighting other devices.

Supported on a bracket 3, at a suitable distance above the range 1 there is a box 4. The top of the box is normally closed by a hinged cover 5, the said cover being provided with a handle 6 whereby, when the cover is latched on the box and detached from the bracket 3, the said box may be conveniently carried from place to place.

In the box 1 there is a glass jar 7.* The has screwed on the mouth thereof the usual cap 8. Centrally secured to the cap by means 9, there is a fibre block 10. Along one side or edge of the fibre block there is a paper strip 11. Connected by means 12 to the paper strip and to the block 10 there is the burner to ignite the gas.

a copper strip 13 that provides one of the electrodes. onnected to the opposite side or edge of the strip by means 1d, there is the second electrode 15. This electrode is spaced from the block 10 by mica or other insulated washers 16. By reference to Figure 4: of the drawings it will be noted that the electrode 15, from its lower connecting element 14, is extended at an outward angle, as indicated by the numeral 17, and from thence is arranged in a plane with its upper straight or connected portion, as indicated by the numeral 18. Both of the electrodes project a suitable distance below the fibre block 10, and the end 18 of the electrode 15 may be bent a desired distance away from the end of the electrode 13. The electrolyte 1n the jar is indicated by the numeral 19.

The jar is partly lillcd with water with which is mixed an electrosalts. The level of the electrolysis is indicated by the numeral 19, in Figure l of the drawings.

The upper connecting element for the electrode 13 serves as a binding post for a cable 20 that is connected to a plug 21 that enters a wall socket. 1

The upper connecting element 1a for the electrode 15 serves as a binding post for a "that screwed in the handle 29. The outer end of the handle has an eye 31 thereon, and this eye is designed to engage with a book 82 on the box 41-, when the lighter is not required for use.

It will be apparent to those skilled in the art to which this invention relates that when the lighting electrode is brought into contact with the burner 2, after the gas has been turned on, an electric circuit will be completed and a spark will be created at The device may be safely handled, and the lighter when not in use is, as stated, suspended from the hook 352. The intensity of the spark is regulated by adjusting the copper electrode 15 toward or away from the copper electrode 13.

10 plates Having described the invention I claim A rheostat comprising a receptacle containing a liquid and having a threaded neck portion, a flanged capserewed on-said nee for closing; the mouth of the receptacle. :1 fibre block secured to the cap, extendingin \vardly therefrom and designed to be re eeived in the liquid in the receptacle, paper strips along the edges of theblock, vmetal comprising electrodes arranged cables guided through the cap and connected to one of the securing means for each of the electrodes, and one of said conductors designed to be connected to an electric circuit.

In testimony whereof I afiix my signature.
